CAR-SEAT.

SPECIFICATION forming part of Letters Patent No. 683,288, dated September 24, 1901.

Application filed May 2 1901. Serial No. 58,457- (No model.)

To all whom it may concern:

Be it known that I, LOUIS J ANSON, a citizen of the United States, and a resident of the city of New York, borough of Brooklyn, in the county of Kings and State of New York, have invented a new and Improved Oar-Seat, of which the following is a full, clear, and exact description.

The purpose of the invention is to provide the frame of a car or similar seat with springsupported shaping-plates so constructed that said plates consist of two or more sections having sliding connection, so that when a cover is stretched over the frame and the seat sustains a weight the tension is equally distributed over the entire upper face of the seat and when the weight is removed the cover will be automatically and smoothly stretched throughout its length, the cover sustaining but little of the tension due to the applied weight.

A further purpose of the invention is to provide a construction of car-seat which will tend to add to the lifetime of the cover of the seat and which will be much more comfortable to the occupant than the ordinary construction of spring-seat.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claim.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure 1 is a perspective view of the improved seat, the cover being partly broken away; and Fig. 2 is a transverse section through the seat, the cover being removed.

A represents the side bars of the frame of a car-seat, and B the cross-bars, extending from one side bar to the other at intervals in the length of the side bars. These cross-bars B are usually made to enter rabbets 10, produced in the inner faces of the side bars at their lower ends, and are secured to the side bars by screws or equivalent fastening devices. Each cross-bar B has attached thereto a series of springs 11, preferably of helical type, and the springs of the cross-bars are made to support shaping-strips C. These shaping-strips are arched and are preferably constructed of a spring material-as, for example, brass or steel, the latter being preferred. The shaping strips or plates may be of any desired width and are attached at their outer ends to the upper faces of the side bars A of the frame in any approved manner. Each shaping-strip O is constructed in two or more sections, usually two sections 12 and 13, as shown in the drawings. These sections are made to slide one over the other at any portion of the shaping-strip, and the free end of the upper section 12 slides beneath a transverse shield 11 on the section 18, so that the cover 19 provided for the seatwill not interfere with the movement of the sections relative to each other.

Bolts or rivets 15 are passed through the two sections 12 and 13 of a shaping-plate C, where their ends overlap, and these rivets or bolts are fitted snugly to the upper section 12, but enter longitudinal slots 16, produced in the opposing section 13, so that the movement of the two sections of a shaping-strip relatively to each other is limited. The bolts or rivets 15 are provided with washers 17 at their lower ends, and the lower extremities of the bolts or washers are headed or provided with nuts. One of the rivets or bolts 15 may be, and usually is, utilized to secure the upper end of a central spring 11 in proper position relatively to a shaping-plate, while the upper ends of the other springs of the series are secured to the sections 12 and 13 of the shaping-plates by bolts or rivets 18. Practically a shaping strip or plate has hearing on the helical springs 11 at various points between its ends.

The cover 19 may be of any suitable construction and completely conceals the shapw ing strips or plates, being drawn tightly over them and secured to the body portion of the frame of the seat in the customary manner.

It will be observed that when a seat is constructed as has been described and the seat is occupied it will comfortably accommodate the occupant, and the burden of the pressure due to the presence of the occupant will be sustained largely by the shaping strips or plates, and said pressure will be equally distributed over that portion of the seat occupied, so that the cover 19 will not be subjected to undue tension. As soon as the seat is occupied the sections of the shaping strip or strips brought directly under pressure and those that are adjacent slide inward and prevent the seat from unduly sagging, and the moment the seat is unoccupied the sections of the shaping-strips formerly under pressure move outward and the shaping-strips assume their normal arched shape, bringing the cover 19 under proper tension and rendering the cover perfectly smooth.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- In a car-seat, the combination, with a bodyframe and helical springs carried by the said frame, of shaping-strips of a spring material, constructed in sections, which sections meet and slide one upon the other at their inner ends, the outer ends of the sections having attachment to opposite members of the bodyframe, the inner end of one section of a shaping-strip being provided with slots, rivets or In testimony whereof Ihave signed my 0 name to this specification in the presence of two subscribing witnesses.

LOUIS JANSON.
